Application filed September 23,1915. Serial No. 52,151.' l i 'To` all tvhom t may concern 4 Bei known that I, BERTRAM CoHEN,a

:subject of the King .of England, residing at This invention relates to an improvement in tire-protectors, its object being to prolvide an attachment for ya motor-vehicle, bi-

cycle, etc., having pneumatic tires, arranged to pick or scrape oli" the tire, while the wheel rotates, any protruding .element which might .be forced through the shoe or casing 'and also through the inner tube, when said element. touches the ground. In other words,

should the casing pick up a tack, nail, screw frequent contactl with the ground, dur'- ing continued'revolution of the wheel. '30

or other sharp article, which frequently happens, thek point'of which partly pierces the tire casing, theother end' thereof protruding from the surface of the casing, the saidarticle will -be picked out` or scraped off the casing as soon as the scraper, which forms part of my invention, comes in contact therewith,Y consequently thel picked-up ar# ticle will not be forced farther into the tire I will now proceed to describe' my invention in detail, the essential features of which will be summarized in the appended' claims, reference being had to the accompanying' drawing, forming part glhereof; wherein-l i Figure 1 is an end view of one of the rear wheels of a motor-vehicle, a portion of the axle-housing being also shown equipped with my improved protector; Fig. 2 is asimilar view of lone of the `front wheels, illustrating my improved protector secured to the .steering-'knuckle arm; Fig. 3 is a fragmentary side view of a ypneumatic tire illustrating the scraper portion of my pro-y tector; Fig. 4 is -a fragmentary perspective View illustrating the manner of connecting the scraper and support therefor; and Fig. 5 is gn enlarged top plan view'of the scraper.

vAs' herein illustrated my :improved tire protector consists, of a support 1 and scraper 2. For the purpose of adjustment, I preferably form the support 1 out of'a plurality .of members 3 and 4 adjustably connected by bolts 5 which pass through aslot 6 in the member 3"-(Fig. 4) and an alining slot in i the'mcmbcr 4. The scraper 2f, which is pref-- erably semi-circular to correspond to'y the' contour of the tire casing,- as shown, carries an extension 7 which is pivotally `secured as aty 8 :to the support-'member 3. To adjustably secure the scraper to the support, I provide a wing-nut` 9 which engages the threaded end of a binding-bolt 10. lWhen the wing nut/" is screwed up tightly the scraper 2 will be securely held in position upon the support therefor.

The lower member 4 of the support 1, for the rear tires, is secured'to any xed part of the'chassis, as for instance to the axlehousing 11, by bolts 12 or otherwise. 'The .1' f d OFFICE v.

lower member 4 of the support for. the V scraper of the frht tires is mounted to move with the steering-knuckle 13,y and in this instance I yveA shown it as secured to the steering-arm 14 by a clamp 15, but of course I do not limit myself to this particu.

lar manner of securing the support 1.

When the scraper2 is properly adjusted relatively lto the tires, it willbe positioned l slightly away therefrom (one-eighth of an inch for instance) in order that it will not contact with the tires, butbe suiiciently close thereto in vorder to'pick up or scrape off' any protruding article, such as a tack, forI in# v stance, illustrated by 16 in Fig. 3.

It will be quite evident that the scraper 2 will pick of lany protruding article which may attach itself to the tire, thereby pre venting' the danger of a puncture from such article by, being forced through the tire-ele- .9o

ments by` frequent contact with the ground as the wheel continues to revolve. It will be also apparent that the scraper 2 wlll be stationary and any protruding article picked up by the tire will be scraped oif the same as soon as it comes in contact with. the scraper.

Should it become necessaryv to apply chains to the rear tires, thescrapers 2, ad-

jacent said tires, will be swung to the dotted position 17 Fig. 1. Should it become necessary to remove the frontor rear tires, the scraper 2'therefor cany be swung away therefrom. ,i a It will be 'seen that I can adjust the sera-pby loosening` the bolts 5 and sliding Ythe members 3 and 4 inwardly or outwardly as 165V ers .relative to the tread -portion of the tires'f` To limit the inward f ovement of fthe scraper 2, IV provide a stop-pin. 18 which, l

when the scraper is in. position adjacent the tire, will contact with the support member 3 and prevent the scraper from coming in contact with the shoe of the tire.

The'scraperslQ are preferably made upof slidably connected members 2, 2b, held in slidable relationship by' a. bolt or pin 2, whereby the scraper may be adjusted for vuse in connection with tires of varying widths.

` Having now described my invention what I claim and desire to secure byxLe'tters Pat ent is:

l. A tire protector comprising a support' consisting of a plurality of slidably connected members arranged for securement' to a vehicle having pneumatic tires, a scraper pivotally secured to one of said support members, and arranged to be positioned adjacent a tire but out of contact therewith, and means to lock said scraper in adjusted positions.

2. A tire protector comprising a support,

and a scraper movably connected thereto,.

said scraper comprising a plurality of adjustably connected members.
